'APPARATUS FOR DRAWING SODA-WATER AND OTHER BEVERAGES.

SPECIFICATION forming part of Letters Patent No. 248,918, dated November 1, 1881.

Application led August 15, 1881.. (No model.)

To all whom it may concern Beit known that WILLIAM P. CLARK, of the town of Medford, in the State ot' Massachusetts, have invented Improvements in Apparatus for Drawing Soda-Vater and other Beverages, of which the following` is a specitcation.

This invention relates to certain improvements in the apparatus shown and described in Letters Patent of the United States No. 222,869, granted to nie on the 23d day of December, 1879; and the invention will, in connection with the accompanying drawings, be hereinafter fully described, and specifically de- -iined in the appended claims.

' Figure lis a side elevation of the apparatus as assembled. Fig. 2 is a longitudinal vertical section of Fig. l. Fig. 3 is a horizontal section taken on line G, Fig. 1, the axial locking-spindle y and a part of lever x being shown in plan. Fig. 4C is a horizontal transverse section taken on line H H, Figs. and 2. Fig. 5 is a perspective view of the lower portion ofthe valve, the removable face being shown in sectional perspective. Fig. 6 is a perspective view of the upper portion of the valve-stem, and also of the valve-sleeve. Fig. 7 is a perspective View of the packing-holder, with the packing inserted therein. Fig. 8 is a perspective view of the valve-lever, a portion ofthe handle being broken away. Fig. 9 is atop or plan view of the base or bed, and showing the position of the packing-holder therein, partly by dotted lines, with packing therein inserted. Fig. l0 is an inverted or under-side plan view of the valve-sleeve and the detachable valve-face.

In said views, a represents the metallic base or bed, which is designed to beseated upon the marble slab or other body to which the apparatus is to be attached.

Upon bed a is formed the raised portion b, through which is formed a passage or slot for the packing-holder o, as also a connecting vertical passage in which the valvular devices are arranged, as will be described.

Upon the under side of bed a are formed.

the inlet and outlet tubes d d, by means of threaded nuts upon which the apparatus is secured to the slab or other body upon which it is seated, and through which said tubes pass, in the usual manner, and to which the usual conduit-pipesare to bc coupled. Said tubes d d may be so constructed and arranged as to serve as the immediate or actual conduits of the liquids passing through the apparatus; or the small inclosed tubes e may and preferably are employed, as shown, in order that the liquid shall pass through purer and less corrodible metal than tubesd would necessarily be coinposed of. 6o

The packing-holder c is formed of metal, hard rubber, or other rigid material, and with a circular passage through it so positioned that when the shoulders IL h are in contact with the raised portion b packing f will be coincident with the vertical circular passage in said part b. In bed a are formed two vertical passages coincident with the axial passages in the interiortubes,e, andin packingfare two passages,

g, which coincide with said passages in bed a, 7o as is clearly shown in Fig. 2. An externallythreaded sleeve or wall, i, is formed upon part b, with an axial passa-ge coincident with that in b, and a common compressionnut,j, is internally threaded to tit to wall i. A sleeve or cylinder, 7c, is formed with its lower and larger section to fit the passage in part b and wall t', while its upper and diminished section fits the upper and non-threaded portion ot' the nut j, and the shoulder thus formed on said sleeve 8o by the disparity of the diameter of its two sections is engaged by the shoulder in the nut caused by its two different internal diameters, whereby the downward action of the nut serves to firmly seat the lower end of the sleeve upon the perforated packing fadjacent to the periphery thereof. A valve, Z, is formed with a diameter to t the lower and larger section ot' the passage in sleeve 7c, while its stein m lits the upper and smaller section of the passage 9o in said sleeve.

Upon the lower end or face of valve Z is secured a detachable disk-like face, o, formed of the most indestructible metal, and secured to nthe valve by an axial screw, as shown in Fig, 2, it being held from rotation by the tubes pp, Fig. 5,which are secured in the end of the valve andentercoincidentholesinsaiddisk. (Shown in said Fig. 5.) Said tubes constitute a continuation of the small passages before described, 10o which lead from the small tubes e up through bed a, packingf, disk o, said tubes p, and the lower portion or collar s of valve l, to the concentric groove o, Figs. 2, 5.

Between the external shoulder of valve l (at the intersection ot' its body and stem m) and the internal shoulder iii sleeve k a ring-packing, t, is interposed, and hence, when the compression-nutj is forced down, it not only seats and packs sleeve k on the disk-packingf, but 1t packs said internal shoulder ot' the sleeve upon said ring-packing t, and the i'ace of the valve is at the same time packed upon the packingdisk f, so that the liquid which may be admitted (under any desired pressure) through one of the tubes c into the groove in valve l cannot escape in any direction, except through the passage that leads into the other small tube e, and thence through the connected conduit or pipe.

For the purpose ot' partially rotating valve l, in order to bring the passagts in the valve in coincidence with those in packingf,'or t0 break such connection, the usual handle, w, is secured ou stem m by a spline or key, z, which secures the same from torsional displacement, while the axial spindle y, threaded in said handle, and which receives, in part, the downward force exerted by the tablet-knob A, threaded on spindlem, secures said handlefrom vertical or other derangement. For the purpose of arresting the rotation of valve l when rotated by lever m, a portion ofthe upper part of sleeve k is cut away to form the two stops a', (shown in Figs. 4,6,) which by the contact of pins z arrest said valve, and the hub or enlarged portion of lever is formed with a eurtain, b', which extends downward below the head of said sleeve and covers said seats a, thereby concealing the same, and -the spline z, s0 that both said lever and sleeve present a symmetrical appearance.

To prevent the rotation of sleeve k when valve m is actuated, a stud, e,Fig. 10, is formed thereon, which is seated in the slot d', Fig. 9, in the interiorof wall t', which rises from part b.

By forming the inlet and outlet tubes d d both on bed a, instead ot' forming one of them thereon and then connecting the other removably with such fixed tube, as in my said patent of 1879, important advantages are derived, among which are the facts that the apparatus is more symmetrical and compact, for the reason that the packing-holder j' has the same position relatively to both the inlet and outlet tubes, and the bed and both said tubes constitute a single compact casting, which obviates the necessity of fitting one tube into the other, and by so forming the bed and tubes, and with the non-rotating sleeve and the rotary valve, the liquid is conducted both up and down through the same packing, and changes its course from up to down within the valve chamber, and by forming the non-rotating sleeve k to press upon packing f outside the valve a rotary valve may be employed without confining said packing by interlocking it with the inclosing-wall, as would otherwise be necessary. By combining the rigid packingholder e with the packing-disk fthe latter is secured from lateral displacement, especially at such points thereof as are less compactand nnyielding than other parts; and by the arrangementof sleeve k and the valve the pressure in plane upon both packing-disk f and ring t insures a tight joint regardless of the contact of said ring with valve-stein m, or of said disk 'fwith the inclosing-wall, as was necessary in my said patent of 1879; and,besides,by the said construction,the valve is actuated by the mere vibrations of lever x, whereas in my said patent ot' 1879 it was necessary to raise the valve by the slow process ot' the screw thereon in order to give veilt to the liquid; and, lastly, by curtaining lever a', as at b', the unsightly notch in the sleeve is concealed, and by securing the stop-pin z in leverx instead of in stem m, as has been the practice, the lever is not worked loose on the stem by the shocks resulting from the violent opening and closing of the valve, and the impact of the pin with the stop a', and the axial pin y serves both the purpose ot' an ornament and to secure lever av from being worn loose on stem mi; and by forming packing-holder e with a tapering body it is removed or replaced with greatly-increased facility; and by the described arrangement of the sleeve, the valve, its level', and compresl sion-nut the turning up of the latter raises the valve and sleeve and releases the packin g f and its holder c.
